Aggregate of short prismatic Malachite crystals pseudomorphous after Azurite. They are very well defined, have a silky luster on their faces, are partially coated by colorless and very bright small Baryte crystals and are on a botryoidal Goethite matrix, which is very unusual for the locality.

Group of Malachite crystals pseudomorphous after Azurite, one of them clearly dominant, partially doubly terminated and with very well defined faces and edges, some of them selectively coated by small crystals of Cerussite.
Tsumeb Mine, Tsumeb, Otjikoto Region Namibia
Specimen size: 2.6 × 2.3 × 2.4 cm = 1.0” × 0.9” × 0.9”

Aggregate of Malachite replacing dodecahedral Cuprite crystals. The former Cuprite crystals are very well defined, with smooth faces, a uniform green color and are on matrix.A French classic that is with an old German label from an unknown collector that we’ll send to the buyer.

Specimen size: 2.2 × 1.7 × 2.2 cm = 0.9” × 0.7” × 0.9”

Groups of Malachite crystals (after octahedral Cuprite), coated by a late phase of Malachite microcrystals. They are on a Calcite matrix. Pseudomorphs of Malachite after Cuprite are very uncommon at Tsumeb, and even more so with such large crystals.

Specimen size: 6.1 × 5.7 × 3.7 cm = 2.4” × 2.2” × 1.5”

Small groups of Malachite crystals after dodecahedral Cuprite. They have very well defined faces and edges and are on matrix with a divergent spray of acicular Mimetite crystals.The sample, very unusual, is from the Desmond Sacco collection whose label we will send to the buyer.

A novelty for Tucson 2009. The Malachite has replaced very well defined crystals of Azurite, some of them doubly terminated. The matrix is a thin layer of very bright crystals of Chrysocolla. This association is very rare at Milpillas and only a very few specimens arrived to the market.The specimen has been published in the magazine ‘extraLAPIS’ on page 83, number 45, "Kupfer Mineralien"

Acicular prismatic crystals of Malachite on a matrix of crystallized Dolomite. The color and the fact that this kind of Malachite is practically unknown in Touissit made us think it was Olivenite. A further analysis confirmed the crystals as Malachite.
Touissit, Touissit District, Jerada Province, Oriental Region Morocco
Specimen size: 4.2 × 3.3 × 3.3 cm = 1.7” × 1.3” × 1.3”

Very aerial and fine triple stalactitic-botryoidal Malachite growth with small Heterogenite crystallizations near the base, bright and with a black color. We analyzed the Heterogenite and will send a copy of the analysis to the buyer.

Botryoidal growths and coatings with different green shades, from light to dark. They are on a group of Quartz crystals. As is the case with so many specimens in this collection, the sample is of great quality for the locality.

[SOLD]

Groups of primary Malachite crystals. They have simple and very well defined forms and are very bright. The groups are in matrix with small crystals of Quartz. It is from an old find, never repeated later, in spite of the fact that the locality has been repeatedly revisited in recent years.

Specimen size: 8.2 × 7.8 × 5.2 cm = 3.2” × 3.1” × 2.0”

Radial group of very well developed crystals of primary Malachite. They are very bright and have perfect terminations, a very deep color and are on Quartz matrix.
